理论是实践的先导。离开了具体的工作实践，理论也就失去了存在的基础。如果我们离开经济形势、治安形势和改革形势，纯学术性地去研究保安业的发展问题，是没有什么实际意义的。保安理论要发展，就是要为保安工作的发展注入动力、开拓思路、指明方向，必须在实践中求发展... Theory is the forerunner of practice. Left the concrete work practice, the theory also lost the existence foundation. If we leave the economic situation, the law and order situation and the situation of reform, it will be of no practical significance to study the development of the security industry purely and academically. To develop the security theory is to inject impetus into the development of security work, explore new ideas and directions and must seek development in practice.
